Pros & Cons of UV-Coated Polycarbonate Panels

Polycarbonate panels are used mainly to cover greenhouses. Commercial growers rely on them for their durability and superior light transmission. Panels with ultraviolet-resistant coating or integral UV layers are especially popular because they can last for years without yellowing or degrading.

  1. Pro

    • UV light is a major enemy of any plastic, especially polycarbonate. Without a resistant coating or layer, polycarbonate greenhouse panels can yellow and need frequent replacement. High quality panels are usually UV coated and come with a warranty to back up the manufacturer's longevity claims.

    Con

    • High UV climates like Arizona or New Mexico are hard on greenhouse coverings. You may find yourself replacing panels more often no matter what they're made of or how much they cost. Also consider how much physical damage the panels might receive. In some circumstances, an expensive, high-grade polycarbonate panel might not make economic sense.

    Conclusions

    • Depending on your application, UV-coated polycarbonate panels may be worth the extra expense, considering their longevity. Just be sure to check out the brand you buy, the warranty and user testimonials.
